What is Labyrinthectomy?

A labyrinthectomy is a surgical procedure that involves the removal or destruction of the labyrinth, which is the inner ear structure responsible for balance and hearing. This procedure is typically performed when other treatment options have failed to manage severe dizziness, vertigo, or hearing loss.

During a labyrinthectomy, the surgeon creates an incision in the ear and accesses the inner ear. The labyrinth, including the semicircular canals and the cochlea, is then removed or disabled using various surgical techniques. This can be achieved through mechanical extraction, laser ablation, or chemical cauterization.

By eliminating the function of the labyrinth, the brain is deprived of signals related to movement and sound from the affected ear. This can help alleviate severe symptoms of dizziness and vertigo, providing relief to individuals who have not responded to more conservative treatments. However, it's important to note that a labyrinthectomy usually results in permanent hearing loss in the affected ear.

Labyrinthectomy is generally considered a last resort option when other treatments, such as medications or vestibular rehabilitation therapy, have proven ineffective in managing symptoms. The decision to undergo a labyrinthectomy is made in consultation with a healthcare professional based on the severity of symptoms and the individual's overall health and preferences.
